will probably work as the clutch disk, i think i'm using the second one, but they all seem to be the same size and fitment, i believe Marks using one like the first one.
Pressure plate is a little trickier to find, first time i found a complete clutch kit from a VW LT 2.8TDI for 50quid, and just used the pressure plate (its the same as the S2 one). Second time round i bought a new pressure plate from All German Parts. Worst case you can buy the cover from VW dealer.
The cover from the lt van was around £100 from tps for a recon unit as was the friction disc but i got them both off ebay at the time of partsdepot for £60 each iirc. Good setup aswell as i got the fly for £45 delivered and machining was £100 so setup was under £300
Oh and if you find a flywheel on ebay get them to send you the bolts as well as you will need the shorter ones.
well it depends what route you take and whats wrong with it.
You cant use your existing plate along with the aforementioned 240mm clutches, they're completely different.
If the existing clutch has failed due to oil contamination (as the one on my avant had) then a new friction disk is probably all you need, as well as fixing the oil leak ofcourse. The flywheel and cover can be cleaned up etc.
If its just worn out, then i wouldnt think its a great idea trying to reuse any bits of it.
As for going back to stock spring plate, the parts mentioned above will give a much heavier pedal than a stock 1.8T clutch, so theres probably nothing to worry about there.
